The sight of the new £56million striker decked out in Gunners gear will bring a smile to the face of every fan of the north London club, and the pictures suggested the 28-year-old is raring to go.

Arsenal were embarrassed last time out when they lost 3-1 to Premier League strugglers Swansea City, and will be hoping to bounce back with a win.

Aubameyang, who last played in Dortmund's 2-2 draw with Freiburg on Saturday, could be on the teamsheet for the match, and will likely link up with Henrikh Mkhitaryan, who he played alongside in Germany.

Here are five questions as the Gabon superstar trains at Arsenal for the first time.

1. Why is he training on his own?

Aubameyang hit the pitches on Thursday morning by himself, while the rest of the Arsenal team were apparently missing in action.

The squad will likely all train together later in the day, which throws up the above question, why was the star at London Colney on his own?

A reason wasn't given as to why the press conference was pushed back, amid speculation Arsenal were about to announce Mesut Ozil's contract extension.

It seems, however, that Wenger was in fact just keen to get on the pitch at London Colney and teach Aubameyang the Arsenal way.

3. Is the Arsenal boss ready to throw him in the deep end?

Considering the fact that Aubameyang was training on his own - ahead of his team-mates in a bid to get match fit - and with Wenger - who, as we now know, skipped a press conference to train with him, it seems the Gabon is definitely set to start against Everton.

As aforementioned Arsenal were embarrassed last time out and are severely lacking in attacking options at the moment.

At Dortmund the forward wore the number 17 shirt, which is worn by Alex Iwobi at Arsenal. As a result he has been handed the number 14 shirt for the remainder of this season.

Next year you can expect to see Aubameyang wearing the number 17 however, as he will want to retain his brand. The fact he's still wearing these boots proves this.

Iwobi can expect a conversation with the striker soon.

5. What can Arsenal expect from the forward?

Aubameyang struggled to make an impact in his last game for Dortmund.

The Gabon international cut an isolated figure playing on the shoulder of the last defender, looking for his team-mates to do something creative for him to finish.

His performance would worry Gunners supporters - who have seen Alexandre Lacazette become cut adrift too many times this season due to a lack of supply - if it wasn't for the fact that the 28-year-old had already mentally left the club.
